will be used as the property names. Alternatively, the column names can be taken from the first row of the CSV.</p>
<p>When converting to CSV, the column template is used to identify which properties to extract from the object and in what order.</p>
<p>If the input is an array then the columns template is only used to optionally generate a row of column titles.</p>
<p>If 'parse numerical values' option is checked, string numerical values will be returned as numbers, ie. middle value '1,"1.5",2'.</p>
<p>If 'include empty strings' option is checked, empty strings will be returned in result, ie. middle value '"1","",3'.</p>
<p>If 'include null values' option is checked, null values will be returned in result, ie. middle value '"1",,3'.</p>
<p>The node can accept a multi-part input as long as the <code>parts</code> property is set correctly.</p>
<p>If outputting multiple messages they will have their <code>parts</code> property set and form a complete message sequence.</p>
<p><b>Note:</b> the column template must be comma separated - even if a different separator is chosen for the data.</p>
